The invention provides an early warning system for the arrival of a bus, comprising an initial station waiting hall, a terminal station waiting hall, a plurality of buses travelling between the initial station waiting hall and the terminal station waiting hall and a plurality of first direction waiting halls and second direction waiting halls which are respectively arranged on two sides of a position between the initial station waiting hall and the terminal station waiting hall; the initial station waiting hall and the terminal station waiting hall are respectively provided with intelligent code converters; a radio frequency identification device (RFID) wireless transmitter is arranged on each bus; first direction wireless receivers and second direction wireless receivers for receiving signals transmitted by the RFID wireless transmitters are respectively arranged in the first direction waiting halls and the second direction waiting halls; and the first direction wireless receivers and the second direction wireless receivers are respectively and electrically connected with an early warning device of a bus stop platform. According to the invention, by adopting the RFID technology to realize the wireless transmission of the signals and using a code identification technology to ensure the accurate mutual identification between the bus and the bus stop platform, the whole system is more humanized and the travel is safer.

The invention provides a monitoring method and a monitoring system based on a mobile terminal. The method comprises the steps of detecting the movement condition of the mobile terminal; detecting the service condition of the mobile terminal for a user; if the movement condition shows that the mobile terminal has movement information, and the service condition indicates that the mobile terminal has at least one piece of contact information, use distance information, use angle information and use information in eyeball use information of the user, starting risk warning. According to the method and the system provided by the invention, detection accuracy on service condition of the mobile phone for the user can be improved, and accurate warning is achieved.

The invention discloses an ultrasonic blind zone processing method for an anti-collision alarm system. The method includes the steps of triggering a blind zone signal processing when reaching the highest alarm level flag bit; if H < / =A, maintaining the highest alarm level flag bit; if H>A and H> / =B for n successive detection periods, outputting an alarm level flag bit corresponding to H, and otherwise maintaining the highest alarm level flag bit, where A<B; and if A<H<B for m successive detection periods, outputting the alarm level flag bit corresponding to H, and otherwise maintaining the highest alarm level flag bit, where A is a first distance threshold, B is a second distance threshold, H is an ultrasonic probe echo distance of the anti-collision alarm system, n>5, and m>5. The method of the invention can well solve the problem that signals jump and disappear in a detection blind zone of a sensor, is conducive to avoiding the driving safety hazard caused by false positives and non-reporting, and greatly improves the active safety performance of driving and the reliability of an intelligent driving assistance function.

The invention relates to a master control hot standby method for a subway on-board broadcasting system. The method comprises a master-slave switching method and a master-slave working method. The master-slave switching method comprises the following steps: preference rules are preset; and according to a set threshold time, each controller makes judgments on status change conditions and decides whether to change a working mode or not according to the preference rules. The master-slave working method comprises the following steps: a controller in a master working mode schedules a train control bus and / or an internal bus to send roll calling data frames, control data frames and self-status data frames; a controller in a slave working mode achieves data synchronization through the control data frames; and the controller in the slave working mode or a carriage controller, on which roll calling is carried out, sends self-status data frames as response frames to respond to the controller in the master working mode. The method provided by the invention has the advantages that automatic switching between the working modes can be achieved, so that the automation level of the system is improved; and the data synchronization between the two controllers can be achieved, so that the problem of broadcast information misreporting of the controllers after the switching is avoided.

The invention discloses a smoke alarm control method based on computer processing and system thereof, relating to the field of smoke sensor. The smoke alarm control method includes that during the debugging, the smoke sensor acquires the environment smoke values and sends the values to an environment test module, the environment test module detects the environment to obtain the environment intrinsic state; the smoke sensor acquires environment smoke data and sends the smoke data to a value weight mean value processing module, the value weight mean value processing module calculates the smoke weight mean value (as shown in the description); the smoke alarm solution module determines whether the smoke value of the current environment is in a dangerous state based on the smoke weight mean value (as shown in the description) and the environment intrinsic state; and if the smoke value is in a dangerous state, a controlled relay is pulled in or disconnected. The invention further discloses a smoke alarm control system based on computer processing. The smoke alarm control method can improve the accuracy of smoke alarm and prevents smoke false alarm or error alarm.
